Porn stars who went mainstream

"Our performers deserve not only safe sets, but the ability to work without fear of assault," a spokesperson for the San Francisco-based company wrote Monday. "Rape or sexual assault, with or without a safe-word, off-set or on, should never be accepted as a hazard of adult production."

The mounting accusations, likened to dozens of women accusing Bill Cosby of rape, come on the heels of Lux and Stoya's damning but separate accounts. Lux claimed Deen not only hit her, but forced her to perform a degrading act on the set of a porn film in 2011.

Fires' charge came to light as Deen resigned from his chairman position on the Adult Performer Advocacy Committee.

The advocacy group said it "recognizes the seriousness" of the allegations made by Lux and Stoya, Deen's ex-girlfriend.

"James Deen held me down and f---ed me while I said no, stop, used my safe word," Stoya, 29, tweeted Saturday. "I just can't nod and smile when people bring him up anymore."
